Voltage Regulators - DC DC Switching Regulators Procurement Notes
Verify the specific suffix ELT12 against official datasheets to confirm the 1.2V fixed output variant. Confirm package type UDFN6 and thermal pad requirements during sourcing. Check availability status as distribution may vary. Ensure compatibility with required switching frequency settings before finalizing procurement orders.
Voltage Regulators - DC DC Switching Regulators Selection Notes
Select this component when a fixed 1.2V output is required from a 2.7V to 5.5V input source. The choice depends on the need for synchronous rectification to maximize efficiency at 500mA loads. Consider the 2MHz/4MHz frequency options for balancing component size versus transient response needs. Verify that the UDFN6 package fits the available PCB real estate constraints.
Voltage Regulators - DC DC Switching Regulators Part Context
This part belongs to the MAX8640 family of tiny synchronous step-down regulators. It shares core architecture with variants offering different fixed output voltages, such as the MAX8640YEXT25+T which provides 2.5V. The family is designed for low-power portable applications requiring small footprints and high efficiency from single-cell lithium-ion batteries.
Voltage Regulators - DC DC Switching Regulators Replacement Considerations
Direct substitutes include other MAX8640 variants with different output voltages if the voltage level can be adjusted externally or if the application permits. Cross-reference with similar 500mA synchronous buck regulators from the same manufacturer series for pin-compatible alternatives.
